By starting the servo motor 2 to rotate forward and reverse, the carrier plate 6 can be driven to move upward or downward, so that the top of the carrier plate 6 can be flush with the bottom of the carriage on the transport vehicle, which is convenient for moving the trolley-type vacuum circuit breaker on the top of the carrier plate 6 into the carriage.

[0023] The fixing mechanism includes a fixing plate 7, and the front and rear sides of the top of the loading plate 6 are fixed with the fixing plate 7. The inner wall of the fixing plate 7 is rotatably installed with a second rotating shaft 8 through a bearing. A handle 9 is fixed to one end of the second rotating shaft 8, and a screw rod 10 is installed inside the other end of the second rotating shaft 8. A first movable plate 11 is fixed to the end of the screw rod 10. The first movable plate 11 is located above the loading plate 6. A telescopic rod 12 is fixed between the fixing plate 7 and the first movable plate 11. Second movable plates 13 are fixed at both ends of the first movable plate 11. A fixing rod 14 is installed with a thread passing through the interior of the second movable plate 13. The second rotating shaft 8 and the screw rod 10 are threadedly connected. The telescopic rod 12 is symmetrically distributed about the central axis of the first movable plate 11. By rotating the handle 9, the first movable plate 11 can clamp and fix the trolley-type vacuum circuit breaker front and back. By rotating the fixing rod 14, the fixing rod 14 can clamp and fix the trolley-type vacuum circuit breaker left and right, thereby ensuring that the trolley-type vacuum circuit breaker can be fixed during transportation.

[0024] The loading and unloading mechanism includes a plate body 15, and the front and rear ends of one side of the loading plate 6 are fixed with the plate body 15. A transport plate 17 is rotatably installed between the plate bodies 15 through a third rotating shaft 16, ensuring that the transport plate 17 can be reversed around the central axis of the third rotating shaft 16, so that the end of the transport plate 17 can contact the ground, so that the transport plate 17 can be in an inclined state, which is convenient for the trolley-type vacuum circuit breaker to be pushed to the top of the loading plate 6 through the rollers and the transport plate 17 at its bottom.

[0025] A vertical plate 18 is fixed to the top of the plate body 15, and a bolt 19 is threadedly installed through the top of the vertical plate 18. The end of the bolt 19 is engaged in the inside of the limiting hole 20. The limiting hole 20 is opened on the side of the transport plate 17. The position of the transport plate 17 can be fixed by the bolt 19.

[0026] A roller 21 is installed at the bottom of the base plate 1. The roller 21 has a self-locking function, so that the transfer vehicle can be fixed in one position. The roller 21 is an existing product and will not be described in detail here.

[0027] A push rod 22 is fixed at the front and rear ends of one side of the base plate 1, a controller 23 is installed on the top of the push rod 22, a rechargeable battery 24 is installed inside the base plate 1, the controller 23 is electrically connected to the servo motor 2, the controller 23 can control the servo motor 2, the rechargeable battery 24 is electrically connected to the servo motor 2, and the rechargeable battery 24 can supply power to the servo motor 2.

[0028] Working principle: When using the circuit breaker transport vehicle, first rotate the bolt 19. Since the bolt 19 and the vertical plate 18 are threadedly connected, the end of the bolt 19 is separated from the limiting hole 20, so that the transport plate 17 is out of the fixed state. Then, the transport plate 17 is reversed by the third rotating shaft 16, so that the top of the transport plate 17 contacts the ground, so that the transport plate 17 is in an inclined state, and then the roller 21 is self-locked, and then the handcart-type vacuum circuit breaker with its own roller is pushed to the top of the loading plate 6 through the transport plate 17;

[0029] Then, the transport plate 17 is rotated forward to a vertical state, and the bolt 19 is rotated reversely so that the end of the bolt 19 is engaged with the limiting hole 20, thereby completing the fixing of the transport plate 17;

[0030] Then, the handle 9 is rotated, and the handle 9 drives the second rotating shaft 8 to rotate. Since the second rotating shaft 8 and the screw rod 10 are threadedly connected, the screw rod 10 drives the first movable plate 11 to move closer to the trolley type vacuum circuit breaker, and the telescopic rod 12 is extended. Under the action of the front and rear first movable plates 11, the trolley type vacuum circuit breaker is fixed front and back. Then, the fixing rod 14 is rotated. Since the fixing rod 14 and the second movable plate 13 are threadedly connected, the fixing rod 14 fixes the trolley type vacuum circuit breaker left and right.

[0031] The fixed trolley-type vacuum circuit breaker is transferred to the back of the transport vehicle by the transfer vehicle, and then the servo motor 2 is started. At this time, the servo motor 2 drives the first gear 3 to rotate, and then the first gear 3 drives the four second gears 4 and the four first rotating shafts 5 to rotate at the same time. Since the first rotating shaft 5 and the loading plate 6 are threadedly connected, the loading plate 6 moves upward until the top of the loading plate 6 is flush with the bottom of the compartment on the transport vehicle, and then the handle 9 and the fixing rod 14 are rotated in the opposite direction to make the first movable plate 11 and the fixing rod 14 away from the trolley-type vacuum circuit breaker, and then the trolley-type vacuum circuit breaker on the top of the loading plate 6 is pushed into the interior of the compartment to facilitate the loading of the trolley-type vacuum circuit breaker.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
